Write a class that uses while loops to perform the following steps:
a) prompt the user to input two integers: firstNum and secondNum. firstNum must be less than secondNum (data validation should always be a while loop with lead and looping prompts)
b) output all the odd numbers from firstNum to secondNum. Also output all the even numbers from firstNum to secondNum
c) output the sum of all the even numbers from firstNum to secondNum
d) output all the numbers from firstNum to secondNum and their squares
e) output the sum of the squares of all the odd numbers from firstNum to secondNum
